- Brief Summary
This open-label, prospective, single-arm, multicenter study will evaluate the relationship of the markers of inflammation and progression-free survival (PFS) in participants with previously untreated metastatic colorectal cancer. The study consists of two phases: Phase A treatment: oral capecitabine plus infusional oxaliplatin (XELOX) plus bevacizumab, or modified infusional 5-fluorouracil (5-FU), leucovorin (LV) and oxaliplatin (mFOLFOX6) plus bevacizmab administered until first disease progression. Participants will then continue with Phase B treatment: infusional 5-FU, LV and irinotecan (FOLFIRI) plus bevacizumab until second disease progression. The anticipated time on study treatment is 4 years.

Name Time Method Association Between Neutrophil to Lymphocyte Ratio (NLR) [NLR ≤5 Versus NLR >5] and Progression-Free Survival (PFS) as Assessed by Hazard Ratio Baseline up to disease progression, death or end of study (up to 4 years) NLR was calculated from the laboratory values as the ratio of Neutrophils to Lymphocytes. PFS was defined as the time from the start of initial treatment to documentation of first disease progression or death from any cause, whichever occurred first.

Each of the 8 scales is calculated based on the answers to 3 questions. Each question is given an answer dependent utility score (0 \[worst\] to 1 \[best\]) and then these scores are combined using a multiplicative model to get the normalized scale score value, each scale ranging between 0.0 (representing death) and 1.0 (representing full health).

European Quality of Life 5-Dimension (EuroQol-5D) Utility Score: Phase A Baseline, every 8-9 weeks thereafter, end of treatment (EOT) (30 days after disease progression [up to 4 years]), survival follow-up 12-weekly visits (up to 4 years) [Detailed time points are presented in the category titles] EQ-5D is a standardized generic preference based health related quality of life instrument. It records how one's health is "today" and consists of a descriptive system. The descriptive system is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression. Each dimension on the EQ-5D involves a 3-point response scale which indicates the level of impairment (level 1 = no problem; level 2 = some or moderate problem\[s\] and level 3 = unable, or extreme problems). Level of problem reported in each EQ-5D dimension determines a unique health state which is converted into a weighted health state index by applying scores from EQ-5D preference weights elicited from general population samples. This generates a unique description of the subjects' health status, which is valued between 0 (representing death) and 1 (representing perfect health). Higher the score, the better the quality of life.
